Notes on Percent Change

When you use Notes on Percent Change, you build a clear understanding of how quantities increase or decrease over time. This playsheet helps you collect important information, formulas, and examples so you can calculate percent change confidently. Instead of relying on guesses, you learn how to express differences between two numbers in a meaningful way that helps explain what happened.

As you take notes, you’ll notice that percent change always starts with an original value and a new value. You subtract the two numbers to find the amount of change, divide by the original amount, and then multiply by 100 to turn it into a percentage. Writing down each step in your notes helps you remember the process and apply it correctly in future problems.

You’ll also enjoy discovering how percent change appears in real-life situations. You may track price drops during sales, measure growth in plant height, compare scores on tests, or examine changes in population. Understanding these changes helps you make thoughtful decisions and interpret data more accurately. Recording examples in your notes allows you to see how percent change works beyond math worksheets.
